Sprocket Size

 What would be a good size (teeth) for a 600R that has been converted for the street. Mine has the stock rear sprocket which is fine for the dirt but very low for the street. I live in the country and often hits speeds of 55+mph.

15/45 seems to a good all around gearing for me. 1st is a little high for really tight trails so I avoid them but crusing at 60-65 is nice when heading to another (offroad) riding area. Less shifting is also a benefit.

I'm in the same situation. I will be trying the 15/45.

I'm also installing the XR650L primary drive gear and clutch basket. It's 2 teeth different than the XR600R's setup.

I ride 80% street and 20% dirt.
